Code Syntax Style: Multiple Attributes

Multiple attributes in C# can be written in different ways: you can join several attributes in the same square brackets section or use several sections for different attributes. ReSharper allows you to specify the style for multiple attributes and enforce this style in the desired scope.

Your preferences may say that the attributes should be on separate sections:

... or into a single section:

Attribute style settings are not applied to generated code. By default, ReSharper provides the list of file masks and regions for generated code typically produced by Visual Studio (for example, Windows Form Designer-generated code). If necessary, you can edit the list of generated items on the Code Inspection | Generated Code page of ReSharper options.

Another option to enforce preferences for multiple attributes in a bulk mode is code cleanup. You can either run code cleanup with the default profile Default: Full Cleanup or run the cleanup with a custom profile solely targeted at your specific task as described below.

To apply attributes style with custom Code Cleanup profile

Select ReSharper | Options in the main menu.

Go to the Code Cleanup settings page: Code Editing | Code Cleanup.

Create a new profile as described in the Code Cleanup section. In the Selected profile settings section for the new profile, tick the Arrange attributes check box. Optionally, you can enable other code cleanup tasks in this profile.

Click Save to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To drop-down list. For more information, see managing and sharing resharper settings.

Select the scope where you want to enforce your preferences:

Set the caret anywhere in the file to enforce your preferences to the file.

Select one or more items in the Solution Explorer to enforce your preferences in the files under these nodes and their child items.

If you want to apply attributes style without opening the Code Cleanup dialog, you can bind the default Reformat Code profile to the silent cleanup and run it simply by pressing Ctrl+Shift+Alt+F. You can also create a custom cleanup profile that would combine applying attributes style with other code style tasks.

Configuring preferences for attributes style

Your attributes style preferences are saved using the mechanism of layer-based settings. Among other things, this mechanism allows you to maintain different preferences for different solutions as well as to keep these preferences under a VCS and automatically share them with your team members.

To configure preferences of attributes style

Go to the Code Editing | C# | Code Style page of ReSharper options.

In the Attributes category select the value for the Join or separate attributes in section according to your coding practices/standards.

ReSharper also provides multiple formatting rules for attributes. To see and configure these rules, open ReSharper options (ReSharper | Options), type attribute in the search box, and check matched items on pages under Code Editing | C# | Formatting Style.

Click Save to apply the modifications and let ReSharper choose where to save them, or save the modifications to a specific settings layer using the Save To drop-down list. For more information, see managing and sharing resharper settings.

You can also change your preferences for arranging multiple attributes right in the editor, where corresponding issues are highlighted:

To change preference for explicit/implicit modifiers in the editor

Set the caret to a code issue highlighted by a ReSharper's inspection.

If you need to save the modified style preference in a shared settings layer, click on the Configure code style menu item or press Enter when it is selected. ReSharper will open the Code Editing | C# | Code Style page of ReSharper options where you can modify your preference as needed, click Save To and then choose the desired settings layer.
